WHAT IT DOES
May support bone health and density.

DOES IT WORK?
Good pick. Strontium shows some promise for bone health, particularly in postmenopausal women. However, the evidence isn't as strong as other bone-supporting nutrients like calcium and vitamin D, and there are some safety concerns at higher doses. It may be a helpful addition for some, but not a foundational supplement for everyone.
